But on Wednesday, widowed father of four Hendry disputed the reading and asked Blackpool Magistrates to have the case adjourned so his metabolism could be tested. The court heard that Hendry admitted drinking before driving his blue Ford Focus, but argued the amount of alcohol he drank over a certain period of time should not have put him over the limit. His lawyer Glyn Lewis - who has previously represented a string of celebrities over his expertise in exploiting motoring legal loopholes - said: 'Usually we go to sentence and it is inevitable he would have to be disqualified because he has entered a guilty plea because he accepts the facts. 'But the instructions I have over the amount of alcohol consumed and the time period, when you do the calculations they don't correlate with the figure he has given. 'There are two possibilities - one is because of the fact that he has got some alcohol in his system he is unaware of and the other is quite rare is we have somebody whose metabolism is such they provide a specimen of breath which does not correlate with the reading of blood. 'We have had a forensic scientist give us an indication that the figures provided by the defendant don't correlate with the figures given by the sample.

'We accept the prosecution's case - the police followed him, he wasn't driving erratically, nothing unusual about that, he accepts that - the question is why is this alcohol reading being given that is being investigated. 'We can establish what he consumed and when it was because there are receipts. 'Mr Hendry might have to be tested for his metabolism in the lab with a reconstruction of the whole evening's events. The ratio between breath and blood is not the same for everyone. 'If our investigations don't have foundation in science we would bring it back to court and have it dealt with. Mr Hendry wants the matter to be dealt with as quickly as possible.' The court agreed to adjourn for a 'special reasons' hearing  in which Hendry will call evidence from a forensic service scientist and two civilian witnesses who were with him on the night of the incident. Hendry - who arrived for the hearing in sunglasses and a grey suit - had 63 microgrammes of alcohol in 100 milliltres of breath- the legal limit is 35mg.
